Here are some images showing the different hood options:
1. Included Septon hood
2. LH-40N
3. LH-90IIS
All attach to lens via the 52mm filter thread. The LH hoods are about half the height of the included Septon hood, but they don’t offer front filter threads and require a 39mm front cap. The included hood is longer, but it has a 52mm filter thread on the front, and the same 52mm cap can be used on either the lens or the hood.
The opening on the included hood is slightly smaller than on the LH hoods.
I also included in the images a 3D-printed adapter I made to hold the glass from a 49mm UV filter. It sits underneath the hood and is ideal for those who want the most compact setup with both a UV filter and a hood for the Voigtlander 40mm f/2 Septon Aspherical.

Nor do I think that someone is making a decision to get one or the other of those two lenses. Voigts are typically a compliment to an AF lens, not a replacement.
This is true, but for me I'd prefer to complement the lightweight 40/2 Z with the more expressive, heavier 40/1.2 Nokton. (I know your Nokton feelings, don't worry.) I don't really see the benefit in having two lenses that do more or less the same thing and only differ in having AF or not.

B&H offered to lend me BOTH the Septon and 40 Nok for my review, best news all week after this thread
I think the car show photos are pretty good examples of how pleasing it can be in the center and in the focal plane but just kinda wacky in the bokeh even in the beginning of the outer third of frame.
The bokeh is giving me Contax G 35mm f/2.0 vibes, though perhaps not as extreme as that.
Samples 6: Car show at various distances with Sony A7CR
High contrast lighting, around 11-12am.
Vignetting and distortion were not corrected in any of the samples. Most images use the Cobalt Kodachrome profile (1987 version), with a few using Adobe Color.
These pictures do have more 'bite' -- that high contrast and intense colour Kodachrome look I remember. Is that due to the Cobalt profile? In which case I might add it to my other Cobalt profiles!
I received the 49mm UV filter today to test with the 3D-printed filter adapter that sits behind the hood. This setup works with the included Voigtlander 40mm f/2 Septon hood as well as the more compact alternatives I shared earlier.
Here are some photos of the 3D adapter with the glass transplanted from the 49mm UV filter.

The adapter was specifically designed for the UV filter I mentioned above. Using glass from a different filter might work, but results are not guaranteed.

Fred, let me make sure I get this right, the included/original allows for the use of filter (52mm) and then the hood on top, but you are want to use this one with a smaller footprint?

All three hoods, the included one as well as the LH-40N and LH-90IIS compact options, allow a filter to be added before or after the hood. To keep the setup as compact as possible, the 3D adapter lets you place UV or ND filter glass behind the hood without adding any extra height, so you still get both hood and filter protection in the smallest footprint.
Since compactness is one of the strengths of this lens, it's a nice solution.

The LH-40N absolutely has filter threads on the front (39mm).
By the way, the whole idea of using the more compact hood options (LH-40N and LH-90IIS) came from @Juha Kannisto, who experimented with it when he first got the lens. Thanks for that!
It's also worth noting that this is entirely optional, as the included hood works perfectly on its own.

Aren't all these hoods quite ineffective?
Depends on what you want to do with them. I like hoods as a bit of protection against accidental fingerprints and elements and smallest lenses go best with smallest hoods. These type of hoods work fine for those purposes even if other types might block some more light. I personally dislike long and heavy hoods, especially when combined with small and light lenses.

Sure, I get that and I have about the same idea. But the hood shown by Fred in post #9 doesn't seem to help much about anything. A 10mm or so longer hood can't be a problem, can it? (Just don't use ventilated hoods on cameras with no rangefinder viewfinder...)

If the key selling point is the thinness of the lens (30mm) and one really likes pancake lenses and that aspect of it, adding 10mm to that already feels quite long. I like adding just the bare minimum or could also use it without a hood but adding a ~3mm tiny hood is still a plus with the protection aspects. CV lenses are usually good performers shooting against strong light sources even without hoods and I also never felt like there was a problem with any sidelight when shooting with the Septon + LH-90IIS. Surely when shooting directly against the sun this lens flares a bit more than some, but any hood wouldn't really help there and those flares add some interesting character.
